An experiment was conducted at Department of Botany, University of Karachi to explore the efficacy of homeopathic drug pellets for the control of root knot nematode and improved plant growth of crops. Homeopathic drug pellets of Santonine-43 and Kent-20 used at 75% concentration, respectively, showed excellent results in the control of M. javanica infection but also improved the plant height, weight and yield of all tested crops such as mung bean, mash bean, okra and sunflower followed by 50% concentration in contrast to control. However, 75% concentration of Kent-20 pellets were found best in reducing the galls formation produced by root knot nematodes, while Santonine-43 pellets were best in the improvement of growth of tested crop plants.
